Development of a new trail and educational and recreational programs at the Jacksonville Arboretum and Gardens in Arlington this year stemmed in part from a $15,000 state grant.

The 2010-11 Florida Urban and Community Forestry Grant was matched by a donation of more than 4,700 hours of volunteer service, according to a news release.

The new, one-mile Rosemary Ridge Trail is the longest of the park's six trails. Named for the native rosemary that grows there, the trail traverses a xeric hammock, expansive salt-marsh views, lofty pines, scrubby flatwoods and a depression marsh.

A short side trail allows visitors to see the environmentally sensitive Rosemary Scrub area where rosemary and deer moss grow.

In addition to the new trail, nearly 400 trees and shrubs were planted around Lake Ray and invasive plants removed during the past year.

New and improved park programs include guided evening nature walks through the forest and hosting a high-school environmental competition, according to the release.

The 120-acre Arboretum features fresh water stream, salt marsh, baygall, bottomland forest and xeric hammock biodiversities. The park is open during daylight hours daily; admission is free, except for special events.
